Royal Rumble and WCS 94 are both great pins.
My favorite pin of all time - and I mean it! Is Rollergames. I'm on my 3rd game, which is a early production sample I reimported from Germany. It cost as much as my AFM, but to me, it is much better than AFM, and totally worth it.
My Rollergames is one of very few in the world that have 8 drop targets. Most just have 3. If you can look past the theme, it's a great Steve Ritchie layout. The music is similar to BK2K, some people love it, some people hate it. It's the game that got me started in pinball - I played it on route with my wife before we were married, and I remembered the show from growing up - basically combining roller derby with pro wrestling style antics.
I actually have all the episodes of Rollergames on bootleg DVD, took over 10 years to find them. The show was cancelled before the game made it to production.
I really love Rollergames too, it was the game that opened my eyes to owning a pin in my home, my uncle-in-law had it in his garage when we went to visit many years ago. Great layout, fast paced, only downside is the sounds can get a bit annoying but I have spent may hours bashing away on one, very hard to find over here now, I actually can't remember ever seeing another in Australia
